[Ocfs2-users] Re: ocfs2_broadcast_vote ERROR: status = -75 on Fedora 7 kernel-2.6.22.5-76.fc7

[Sunil Mushran]

Ahh... this problem is restricted to mainline. We forgot to
pack the vote message while we were pruning it. This problem
is in 2.6.20 onwards.

I'll have the patch fix attached to that bugzilla once I have
tested it.
